MT4 indicator autoscroll

New comment
 

Hello,

How do you make an indicator autoscroll? I use this indicator that calculates a moving average angle but I need to refresh it al the time. 

 What do I need to change/add so that it will automatically update on new tics/bars ?

Thanks

  1. You already have it. Your problem is else where. Probably exceeding array size. 

  2. fEndMA=iMA(NULL,0,MAPeriod,0,MAMode,Price,i+EndMAShift);
fStartMA=iMA(NULL,0,MAPeriod,0,MAMode,Price,i+StartMAShift);
    Your max look back is StartMaShift (you test End >= Start) so do your loop correctly.
    Your codeLook back handled
       nCountedBars = IndicatorCounted();       
//---- check for possible errors            
   if(nCountedBars<0)                       
      return(-1);                           
//---- last counted bar will be recounted
   if(nCountedBars>0) 
      nCountedBars--;
   nLimit = Bars-nCountedBars;
   ShiftDif = StartMAShift-EndMAShift;      
        mFactor = 100*840/Period()/ShiftDif;
   Sym = StringSubstr(Symbol(),3,3);        
                                            
                                            
//---- main loop                            
   for(i=0; i<nLimit; i++)
    Decrement is unnecessary Contradictory information on IndicatorCounted() - MQL4 forum
       nCountedBars = IndicatorCounted();       
//---- check for possible errors            
   if(nCountedBars<0)                       
      return(-1);                           
//---- last counted bar will be recounted
//   if(nCountedBars>0)                  
//      nCountedBars--;                  
//   nLimit = Bars-nCountedBars;         
   ShiftDif = StartMAShift-EndMAShift;      
        mFactor = 100*840/Period()/ShiftDif;
   Sym = StringSubstr(Symbol(),3,3);        
                                            
                                            
//---- main loop                            
   for(i= Bars - 1 - MathMax(nCountedBars, StartMAShift); i>=0; i--)
    Get in the habit of counting down. (can't use future values to compute past ones.)
 

Thank you very much it works !
